ios - 如何使用带有 Pinterest.sharextension 的 UIActivityViewController 设置 Pinterest sourceURL 和描述

Question

对于 iOS 8，Pinterest 有一个共享扩展。如何设置图片来源网址和描述属性？我正在使用 UIActivityViewController。我是否使用 UIImage、NSURL 用于 sourceURL 和 NSString 用于描述和返回来创建自定义类？我不确定 Pinterest 如何知道设置源 URL 和描述。

Answer 1

假设您正在UIViewController 子类上实现share 方法，下面的代码应该符合您的期望:

objective-C

- (void)share {
    NSString *textToShare = @"Hello Pinterest!";
    NSURL *url = [NSURL URLWithString: @"http://blank.org"];
    UIImage *imageToShare = [UIImage imageNamed:@"so-logo"];
    NSArray *activityItems = @[textToShare, url, imageToShare];
    UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems: activityItems applicationActivities: nil];

    [self presentViewController: activityViewController animated: YES completion: nil];
}

swift (3.0.2)

func share() {
    let textToShare = "Hello Pinterest!"
    let url = URL(string: "http://blank.org")!
    let imageToShare = UIImage(named: "so-logo")!
    let activityItems: [Any] = [textToShare, url, imageToShare]
    let activityViewController = UIActivityViewController(activityItems: activityItems, applicationActivities: nil)

    self.present(activityViewController, animated: true, completion: nil)
}

结果应该是这样的:
